elevator cabs A and B are connected by a short cable and can be pulled upward or lowered by the cable above cab A. Cab A has mass 1700 kg; cab B has mass 1300 kg.A 12.0 kg box of catnip lies on the floor of cab A.The tension in the cable connecting the cabs is 1.91 * 104 N.What is the magnitude of the normal force on the box from the floor?

An elevator cabin has a mass of 364.1 kg, and the combined mass of the people inside the cabin is 180.9 kg. The cabin is pulled upward by a cable, with a constant acceleration of 1.75 m/s2. What is the tension in the cable?

Two blocks A and B with mA = 1.1 kg and mB = 0.88 kg are connected by a string of negligible mass. They rest on a frictionless horizontal surface. You pull on block A with a horizontal force of 6.7 N.

A horizontal force of 88.7 N is applied to a 28.5 kg crate on a rough, level surface. If the crate accelerates at 1.08 m/s2, what is the magnitude of the force of kinetic friction (in N) acting on the crate?

Two boxes A and B are connected by a lightweight cord and resting on a smooth (frictionless) table. The boxes have masses of 12 kg and 10 kg. A horizontal force of 40 N is applied to the 10 kg box. Find the tension in the cord connecting the boxes. O 27.21 N O 29.21 N O 27.65 N O 21.84 N

A horizontal force of 87.2 N is applied to a 40.5 kg crate on a rough, level surface. If the crate accelerates at 1.23 m/s2, what is the magnitude of the force of kinetic friction (in N) acting on the crate?

A lamp hangs from the ceiling of an elevator as it slows to a stop as it approaches the top floor in a building. The tension in the cord holding the lamp is 90 N and the elevator slows at a rate of 3.2 m/s^2. What is the mass of the lamp?

You bring a bathroom scale onto an elevator and press "up". Your mass is 65 kg. If the bathroom scale reads 750 N, (a) what is the acceleration of the elevator? You then press down and the acceleration downward is of the same magnitude. (b) While accelerating downward, you hold a small mass of 100 g attached to a string. What is the tension in the string? This elevator is in the new BU Data Science building where g = 10 m/s². Your work should include free body diagrams

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

A person weighing 935. N rides in an elevator that has a downward acceleration of 1.26 m/s2. What is the magnitude of the force (in N) of the elevator floor on the person?
